Why Texas State Rules Matter

Texas Insurance Code provides robust patient protections that interact with Aetna CVS Health's national policies. Unlike many states, Texas mandates specific timelines for prior authorization decisions and creates binding external review processes through the Texas Department of Insurance (TDI).

For Cerezyme patients, this means:

  • 72-hour response requirement for standard PA requests (24 hours for urgent cases)
  • Automatic approval if Aetna fails to respond within these timeframes
  • Step therapy override rights with specific medical exception criteria
  • Binding external review at no cost to patients through Independent Review Organizations

These protections apply to state-regulated plans but not ERISA self-funded employer plans, which follow federal rules only.

Texas Step Therapy Protections

Under Texas Insurance Code Section 1369.0546, Aetna CVS Health must grant step therapy overrides when providers document that the required drug (Elelyso):

Override Criteria:

  • Is contraindicated or will cause adverse reactions
  • Is expected to be ineffective based on patient characteristics
  • Patient previously discontinued due to ineffectiveness or adverse events
  • Is not in the patient's best interest (creates barriers to adherence, worsens comorbid conditions)
  • Patient is stable on current drug (Cerezyme) and changing would cause harm

Response Timeline:

  • 72 hours for standard requests (automatic approval if no response)
  • 24 hours for urgent cases where delay could cause serious harm
From our advocates: We've seen Texas patients successfully override step therapy requirements by having their hematologist document specific enzyme levels and bone marrow findings that make Elelyso inappropriate. The key is connecting clinical data to the statutory override criteria in your appeal letter.

"Step therapy not completed" Cite Texas override criteria Medical contraindication to Elelyso, prior failure records
"Not medically necessary" Provide FDA approval evidence FDA label, peer-reviewed studies, specialist letter
"Experimental/investigational" Document FDA approval for Gaucher FDA approval letter, established clinical guidelines
"Quantity limits exceeded" Show medical need for specific dosing Weight-based calculations, treatment response data

Continuity of Care Protections

Texas provides several continuity protections for ongoing Cerezyme therapy:

Coverage Transitions

  • Plan changes: Aetna must provide transition coverage for ongoing specialty medications
  • Provider network changes: Continued access during network disruptions
  • Prior authorization renewals: Annual limits prevent repeated step therapy requirements for stable patients

Medicaid Protections

Under 1 Tex. Admin. Code § 353.7, children age 20 or younger with complex medical needs can continue with out-of-network specialists through single-case agreements.

Emergency Supply Rules

Pharmacists can provide 3-day emergency supplies for specialty medications during prior authorization delays, with full dosing maintained for clinical appropriateness.

FAQ

How long does Aetna CVS Health prior authorization take in Texas? Standard PA decisions must be made within 72 hours under Texas law. Urgent cases require 24-hour response. Automatic approval occurs if Aetna fails to respond within these timeframes.

What if Cerezyme is non-formulary on my plan? Request a formulary exception alongside your PA. Document medical necessity and why formulary alternatives (Elelyso, VPRIV) are inappropriate through specialist evaluation and clinical evidence.

Can I request an expedited appeal in Texas? Yes, if delay would risk serious health consequences. Mark your appeal "urgent" and have your physician certify that delay could cause harm. Texas requires 72-hour decisions for expedited external reviews.

Does step therapy apply if I've been stable on Cerezyme? No, Texas law protects stable patients. If you're currently stable on Cerezyme, switching to Elelyso could cause harm, qualifying for step therapy override under Insurance Code Section 1369.0546.

What documents do I need for a successful appeal? Essential documents include: denial letter, complete medical records, Gaucher disease confirmation (enzyme/genetic tests), prior therapy failure documentation, specialist letter of medical necessity, and FDA approval evidence.

How much does external review cost in Texas? External review through Texas IRO is completely free to patients. The state contracts with Independent Review Organizations and insurers pay all costs.
